You could use

你可以用

preg_replace('/[.,]/', '', $string);

but using a regular expression for simple character substitution is overkill.

但是使用正则表达式进行简单的字符替换是多余的。

You'd be better off using strtr:

你最好使用strtr：

strtr($string, array('.' => '', ',' => ''));

or str_replace:

或str_replace：

str_replace(array('.', ','), '' , $string);
